UNITED STATES PATENT EErcEe THOMAS BAILEY, OF NElV YORK, N. Y.

SPECIFICATION forming part Of Letters Patent No. 581,227, dated April 20, 1897. Application filed June 10, 1896. Serial No. 594,934. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS BAILEY, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Fireproof Walls and Partitions for Buildings, of which the following is a specification.

My invention consists of improvements in the construction of fire-brick walls and partitions,whereby more substantial and reliable walls and partitions of such construction may be provided.

It also consists of an improved application of means for nailing attachments to the Wall, as hereinafter described, reference being made to the accompanying drawings, in which Figure 1 is a perspective view of an elevator or light-shaft partition constructed according to my invention. Fig. 2 is a perspective view of like partitions or walls of greater length with a part broken out. Figs. 3, 4, and 5 are details on an enlarged scale.

My invention relates more particularly to partitions and walls comprising only one thickness of hollow bricks of the character commonly used in partitions, which consists, essentially, of metallic-posts or studs, or both, and bricks so constructed and arranged that posts and studs employed for staying the walls laterally will be entirely inclosed by the bricks for protection from heat in case of fire, the bricks being formed with special notches in the ends, which meet at the posts or studs for inclosing them.

For corner-posts I use angle-bars a and for intermediate studs cross-forms, as b, or Ts, may be used, and make the bricks c, that are to be laid with one end next to them, with a notch d of such depth that the two bricks meeting at the post or stud will en-- tirely inclose the same within their combined notches and abut each other at their ends, and thus protect them from heat. The joints between the bricks will be pointed with plaster (same as the other joints) for more efiective closure.

The studs are to be placed at suitable distances apart, according to the stability required in partitions too long to be sufficiently stable Without such intermediate studs, but in elevator-shafts where the partitions are short, as in Fig. 1, short stay-rods, as 6, may be inserted through several cornices of brick vertically in any suitable order of arrangement to stay the'walls, and tie-plates, consisting of fiat metallic bars f, may be introduced between layers at intervals, said plates being notched at the ends-to embrace the flanges of the posts for being themselves confined by the posts, with the stay-rods e inserted through ing of such nature that pointed Wire nails,

especially if made of steel, may be driven through the shells into the Wood.

In Fig. 2, I represents the bricks arranged with horizontal apertures extending entirely through them horizontally, but they may be arranged vertically with wood filling in each course or only at intervals, as preferred. When arranged as in Fig. 2, the wood pieces will be inserted in the bricks before the bricks are placed in position, the entire row being connected together and all laid at once.

I claim 1. Fireproof walls of bricks and angle corner-posts in which the posts are inclosed by notches of the bevel ends of the corner bricks abutting on the posts substantially as described.

2. The combination in fireproof walls of metallic posts inclosed by notches 0f the ends of the bricks abutting on the posts, and vertical stay-rods inserted in apertures of the hollow bricks, and extending two or more courses of the bricks substantially as described.

3. The combination in fireproof Walls of metallic posts inclosed by notches of the ends of the bricks abutting on the posts, vertical stay-rods inserted in apertures of the hollow bricks, and extending two or more courses of the bricks and metallic tie-plates inserted between courses of the bricks and engaged by notches in the ends with the posts, said stayrods also inserted through apertures in the plates substantially as described.

4:. In fireproof Walls of hollow bricks and metallic posts inclosed in notches in the ends of abutting bricks, Wood nailing-pieces in- 10 sorted in hollow spaces of the bricks for reeeiving; nails through the shells of the bricks substantially as described.

Signed at New York city, in the county and State of New York, this Mth day of May, A. D. 1800.

THOMAS BAILEY.
